1Correctness issues: 2 3- some eflags manipulation incorrectly reset the bit 0x2. 4- SVM: test, cpu save/restore, SMM save/restore. 5- x86_64: lcall/ljmp intel/amd differences ? 6- better code fetch (different exception handling + CS.limit support) 7- user/kernel PUSHL/POPL in helper.c 8- add missing cpuid tests 9- return UD exception if LOCK prefix incorrectly used 10- test ldt limit < 7 ? 11- fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret) 12- full support of segment limit/rights 13- full x87 exception support 14- improve x87 bit exactness (use bochs code ?) 15- DRx register support 16- CR0.AC emulation 17- SSE alignment checks 18 19Optimizations/Features: 20 21- add SVM nested paging support 22- add VMX support 23- add AVX support 24- add SSE5 support 25- fxsave/fxrstor AMD extensions 26- improve monitor/mwait support 27- faster EFLAGS update: consider SZAP, C, O can be updated separately 28 with a bit field in CC_OP and more state variables. 29- evaluate x87 stack pointer statically 30- find a way to avoid translating several time the same TB if CR0.TS 31 is set or not. 32
